Γεια σας! I have some questions about the greeting "Goodnight!" in Greek. During my studies, I thought about "καλό βράδυ!" but it sounds 'Greeklish' to myself. On the other hand, I discovered a definition of "καληνύχτα" (χαιρετισμός που απευθύνεται το βράδυ, λίγο πριν τον ύπνο) and of "βράδυ" (1: το μέρος του εικοσιτετραώρου που αρχίζει μετά τη δύση του ήλιου, διαρκεί μερικές ώρες και το διαδέχεται η νύχτα, 2:η νύχτα) on the also-free Wiktionary (Βικιλεξικό) website. So, if "καληνύχτα" is just before bedtime, the point is: (1) How do I have to greet somebody at 6:00 PM [if it is 'good evening,' please let me know and also consider one hour later, id est, at 7:00 PM in order to become it as "night"] and at 10:00 PM in the streets of Athens? (2) At 6:00/7:00 PM, is that "night" a βράδυ or a νύχτα? (3) If saying "καληνύχτα" is the verb "καληνυχτίζω," is there a verb for a "Goodnight!" with no relation to bedtime? I thank you so much and I am really sorry anyway since I believe both my questions and my subjects may sound a little boring. I have tried to learn Greek with all my heart and soul as my second language and it is too hard for a trying-to-be-a-self-taught person in the non-result oriented side of South America. I do really thank you! Ευχαριστώ πάρα πολύ!
